Dura Ace Track Cog 15T X 1/8

The Shimano Dura-Ace Track Cog is a fixed-gear cog for track cycling, available in multiple tooth counts to accommodate different gear ratios on the velodrome. Each cog is machined from chromoly steel to run true without lateral deviation, ensuring consistent chain engagement and smooth power transfer at high cadence.

The 15-tooth configuration suits riders seeking a higher gear ratio, whether for sprint events or longer track disciplines. Chromoly steel provides the hardness and wear resistance needed to handle repeated chain load over time. The 1/8" chain compatibility makes it a straightforward fit for standard track drivetrains running single-speed chains.
